In 1912, a man named Melville Dewey-the same mind that gave us the decimal system for libraries-tried to standardize the way rural housewives in Ohio organized their kitchen spice racks. He believed that if every household adopted a single, mathematically sound categorization for cumin and cloves, the collective domestic efficiency of the American home would rise by exactly 14 percent.

It was a beautiful idea on paper, neat and logically irreproachable, but it failed immediately because some families cooked by the color of the ingredients, others by the frequency of the dish, and a few simply by what was tall enough to reach the back of the shelf. A rigid number on a jar meant nothing to a woman whose hands were covered in flour and whose logic was dictated by the proximity of the stove to the window.

The corporate world remains deeply in love with this ghost of Melville Dewey. There are eight distinct ways a contractor’s thumb interacts with a physical page or a digital scroll, and almost none of them involve searching for things in the way a database architect would prefer. We live in an era where “unification” is treated as a moral good, a cleanup operation for the messy, region-shaped habits that people have spent decades refining.

I’m thinking about this today because I recently joined a video call with my camera on by accident, catching myself in a stained t-shirt and a moment of genuine, uncurated confusion before I could hit the “stop video” button. There is a specific kind of embarrassment in being seen in your native state, surrounded by the disorganized reality of your own desk, rather than the blurred, professional background we all project.

Grady has been a mechanical contractor in Mobile, Alabama, for 34 years. He smells like old refrigerant and pine sawdust, and his fingers are thick enough that he has to use a specialized stylus to navigate his tablet on a job site. For the better part of three decades, Grady’s world was dictated by humidity.

When he opened his local supplier’s catalog, he didn’t look for “HVAC Solutions”; he looked for the section that dealt with the 92-percent-humidity days that make the air feel like a warm wet blanket. In his old system, high-efficiency cooling and dehumidification were the front door. They were the first 50 pages because, in Mobile, if you aren’t cooling the air, you aren’t doing anything.

The “Unified” Alphabetical Disaster

Last month, Grady’s primary supplier launched their “Unified Global Catalog Experience.” It was a triumph of UI design, featuring high-resolution renders and a perfectly symmetrical grid. But because the company decided to standardize the navigation for the entire North American market, the heating categories-organized alphabetically-now took up the prime real estate.

Grady opened the app to find himself staring at boiler parts and furnace igniters, items he hasn’t installed since the late nineties. His world had been “unified” right off the front page. To understand why this is a disaster, you have to look at how metadata tagging actually functions in a modern warehouse environment.

In a typical relational database, products are assigned attributes like “BTU rating,” “Voltage,” and “SEER2,” which allow a computer to treat every item as an equal citizen. When a company moves from a logic-based regional hierarchy to a flat-file system, they are essentially telling the database to ignore the geography of the user. They are prioritizing the cleanliness of the data over the relevance of the search.

Nova V., a historic building mason I know who specializes in the lime-wash restoration of 19th-century brownstones, understands this better than most. She once pointed out to me that you cannot use the same mortar mix for a north-facing wall as you do for a south-facing one, even on the same house.

“The sun changes the chemistry of the cure, meaning the ‘standard’ mix is actually a recipe for failure on at least half the building.”

When we flatten the way people shop, we aren’t just changing a layout; we are erasing the informal wisdom that regions have built up. In the South, a “split system” isn’t just a category of appliance; it’s a specific solution to the problem of slab-on-grade construction where there is no basement for a furnace. In the Northeast, that same category might be viewed as a supplemental heating source for a cold bedroom above a garage.

By forcing both buyers into the same “Unified Residential Category,” the catalog designer is stripping away the context that makes the purchase make sense. This process often disregards the ASHRAE climate zones-the seven distinct regions of the United States defined by temperature and moisture-in favor of a one-size-fits-all digital architecture.

There is a subtle tyranny in the “average.” A unified catalog is designed for an “average” customer who does not exist. This hypothetical buyer lives in a place where it is 65 degrees year-round and they have no preference between a heat pump and a furnace. But out in the world, the person using the tool is either Grady in Alabama or a facility manager in a snowy corner of Maine.

When the tool stops reflecting their reality, they don’t just get annoyed; they stop trusting the tool. They start calling the branch office and asking for a human, which defeats the entire purpose of the digital “efficiency” the company was trying to buy. The irony is that a well-organized hub doesn’t have to be a flat one.

It is possible to provide a comprehensive view of an entire ecosystem-everything from commercial VRF systems to residential air quality-without steamrolling the regional paths people take to get there. A smart digital structure acts more like a library and less like a grocery store. In a library, the biography section doesn’t move just because the fiction section got a new shipment. The order is consistent, but it allows for different entry points.

When a professional needs to compare systems, they aren’t looking for a “curated experience” that a marketing team thought looked sleek. They are looking for specifications, efficiency metrics, and technical support materials that are grouped in a way that reflects the job at hand.

They need to see the cooper and hunter catalog and understand immediately where the residential high-SEER2 units end and the light commercial accessories begin. They need the hierarchy to be invisible because it is so logical that it feels like their own thought process.

A catalog with one single, identical path for every user is clean, but it’s a terrible way to sell HVAC equipment to a continent with four distinct seasons and six different power grids. The goal should be a centralized hub that organizes the complete lineup into clearly defined segments-Commercial, Residential, Air Quality, Accessories-while still allowing a user to navigate with the regional urgency they bring to the page.

Ignoring the Way People Shop

If you ignore the way a person shops, you are essentially ignoring the person. When Grady closes that “unified” app in frustration and goes back to his dog-eared paper catalog from 2018, it isn’t because he is a Luddite. It’s because the paper catalog still remembers that he lives in Alabama.

It remembers that his priorities are dictated by the sun and the dew point, not by an alphabetical list of parts. Authenticity in business isn’t about having a perfect, unified brand; it’s about having a brand that is honest enough to admit that a buyer in Seattle has nothing in common with a buyer in Miami.

It’s about building systems that are flexible enough to accommodate the “mustard stains” of real-world use. We should stop trying to be Melville Dewey and start trying to be the person who actually has to find the cumin in a dark kitchen at 6:00 PM.

In the end, the companies that win aren’t the ones with the cleanest spreadsheets. They are the ones that realize their products don’t live in a database; they live in attics, in crawlspaces, and on the side of brick houses in 95-degree heat.

A single hub should serve as a map of an entire ecosystem, but it must allow the traveler to choose their own path. Whether it’s a high-efficiency mini split for a sunroom addition or a multi-zone VRF system for a retail complex, the information should be accessible without forcing the user to adopt a logic that isn’t theirs.

We need to stop designing for the screen and start designing for the person standing in front of it, stylus in hand, trying to get the air moving again.
